Be it knowny that l, EDMUND R.. NEBELING, a citizen of the United States, and a resident of the city of New York, Woodhaven, borough of Queens, in the county of Queens-and State of New York, have invented4 anew and: Improved Separable Fastener, of which thev following is a full, clear, andA exact description.

The present invention relates to new and useful improvements in separable fasteners,

and it pertains more particularly to clasps for jewelry, such, for example, as bracelets,`

necklaces, and the like. A

It is one of the primary objects of the 1n"- venti'on' to provide a clasp' for braceletsI that the locking element moves in a direction at substantially right angles to the direction of strain to which the clasp is' subjected in use.

With the above and other objects' iin view, reference is had to the accompanying drawings, in which- Figure 1 is a view in elevation of a portion of a bracelet showing the clasp and its method of attachment thereto;

Fig. 2 is a view in elevation of one of the members of the clasp;

Fig. 3 is a view in elevation of the other member of the clasp; n

Fig. 4 is a longitudinal sectional View of the clasp taken on the line 4-4 of Fig. 2;

Fig. 5 is a perspective view of the several parts of the clasp in disassembled relation.

Referring more particularly to the drawings, the clasp comprises a base 10' and said base 10 is' provided with two side flanges 11, and an end iange 12. This base 10 is cut out as indicated by the reference character 13 to provide a substantially T-shaped opening therein, the purpose of which will be hereinafter described. The base member 10 is also provided with two openings 14C and 15, preferably of circular contour, said openings being formed substantially centrally with respect to the side anges 11. The reference character 15 designates a plate adapted for sliding movement within the base member 10. This plate is cut out'as at 16, to provide'a tongueA 17, and atthe rear of said tongue 17, the plate isf cut out to prOfvide an opening 18. The platel isv depressed as-at 19, toy provide upon its under face a projection 20.- acter 21- designates a closing plate or guide The reference char-A pla-te, and said plate`21is cutout to provide a T-shaped slot.y 22 of substantially the same size as theT-shapedslot lf3-of the base member 10. The referencey character 23- designates a. latch plate, and said latch platef is provided-with a projectinglug or the like 24.

In assembling this -me'mber of the fas tener, the pla-te 15 is positioned withinl the base member 10, after which the) closingy plate'21'is positioned' upon the flanges 11 and 12.v and: suit-ably securedthereto: by means of solder or any other suitable fastening ele.- ment. Afterthe parts havev been sokv positioned, the plate` 23 is positioned on the topy of the plate 21 with itslug 24 positioned within the opening 18 of theplatel This; n plate 23 is secured tothe platel 15 by solder orV upsetting the lug 24'..` The other: member 'of` a plate' 30 provided. withian eye ory they like-31:4

Each of the` membersis provided on one edge` with a wire 32, so shaped as to' provideI eyelets or thek like' 33, to whichl the strands 34s of the pearls or beads: may be secured as indicated in Fig. 1. r

To securev both parts of the clasp together as in Fig'. 1, the eye 31 is inserted in the opening 13 of the base 10. After this has been done, the-plate 2'3f`is moved longitudinally of the. plate'4 21, andi owing to the engagement of the lug 241in the eye' 18-y of the plate 151', the plate 15" will be reciprocated longitudinally of the base v10 and the tongue 17 will'be moved' through the. eye: 31, thus securing the two members of the clasp in locked relation one to the other.

When the clasp is in its open. position, the` the clasp comprises From the foregoing it is apparent that the present invention provides a newand improved form of separable fastener especially adapted for forming the closing means for bracelets, necklaces, and the like, formed from a plurality of single strands of pearls or beads. Furthermore, the clasp is simple in construction and of. relatively loW oost of manufacture. i

I claim:

l. ln a separable fastener, a base member, a sliding plate mounted in the base inember,a closing plate, and an operating member slidably mounted on the closing plate and rigidly secured to the sliding plate whereby upon movement of the operating member the sliding plate will be moved to locking and unlocking position.

2. 'ln a' separable fastener, a base plate having an opening therein, a sliding plate mounted in said base and having a tongue adapted to move across said opening, means for moving said sliding plate, and a member carrying an eye, said eye being adapted to be received in the opening in the base and receive the tongue of the sliding plate to retain the two members of the fastener in closed position.

3. In a separable fastener, a base provided with side flanges and an end flange, said base being provided With a slot, and a plurality of spaced depressions, a sliding plate mounted in said base, the flanges of'said base providing guides for said' sliding plate, means forl sliding said plate relatively to the base, and means carried by said sliding plate and adapted for alternate engagement with said depressions to prevent accidental movement of the plate relative to the base.

4. A separable fastener comprising a. base provided With a substantially T-shaped slot, a sliding plate mounted in the base, a tongue carried by said plate and adapted for movement relative to the im-shaped slot of the base, said plate being provided with a square opening, a closing p'late adapted for positioning upon the flanges of the base, vsaid closing plate being provided With a Hm-shaped slot, an operating plate slidably mounted upon the closing plate, and a lug carried by said operating plate, said lug projecting through the lA-shaped slot in the closing plate and received Within the square opening of the sliding plate whereby movement of the operating plate Will reciprocate the sliding plate to move the latch thereof relatively to the nll"shaped opening in the base.

A separable fastener comprising a base having a transverse and a longitudinal slot, saidvslots communicating one With the other, a plate adapted to be received Within the base, said plate being provided With an opening adapted for registration With the longitudinal slot of the base, a latch formed on said plate and adapted to move transversely of the transverse slot of the base, and means for moving said second-mentioned plate relatively to the base to move the latch member transversely of the transverse slot of the base, as and for the purpose set forth.

6. ln a separable fastener, a base having a transverse and a longitudinal slot, said slots being in communication one With the other, a member having an eye adapted for positioning Within the transverse slot of the base, and means carried by said base and movable transversely of the transverse slot and passing through the eye of the secondmentioned member to secure said members one to the other.

7. ln a separable fastener, a base plate having an opening therein, a sliding plate mounted in said base and having a tongue adapted to move across said opening, means for moving said sliding plate, a member carrying an eye, said eye being adapted to .be received in the'opening in the base and receive the tongue of the sliding platev to retain the two members ofthe fastener in closed position, and means for retaining the sliding plate `against accidental movement relative to the base.

8. lna separable fastener, a base plate having an opening therein, a sliding plate mounted in said base and having a tongue adapted to move across said opening, means for moving said sliding plate, a member carrying an eye, said eye being adapted to be received in the opening in the base and receive the tongue of the sliding plate to retain the two members of the fastener in closed position, and means for retaining the sliding plate against accidental movement relative to the base, said means comprising a projection on the sliding plate adapted for engagement with one of a plurality of openings in the base.
